How to force Postfix to send email for desired IP

Hi..

I have more than one IP for my server, for example :

210.210.210.210
210.210.210.211
210.210.210.212
210.210.210.213
210.210.210.214

Interfaces :
eth1 (main) has address : 210.210.210.210
and aliases :
eth1:0 has address : 210.210.210.213
eth1:1 has address : 210.210.210.214

Domain :

server.com has address 120.120.120.120 (www serwer from other firm)
mail.server.com has address 210.210.210.214
bla.bla.net address 210.210.210.210

Our email adresses :

przemk0@server.com (main domain)
przemk0@bla.bla.net (virtual domain)

Postfix configuration :

---

myhostname = server.com
mydomain = $myhostname
alias_maps = hash:/etc/aliases
alias_database = hash:/etc/aliases
myorigin = $myhostname
mydestination = $myhostname
mynetworks = 127.0.0.0/8, 192.168.0.0/24
relay_domains = $mydestination
inet_interfaces = 210.210.210.214, 127.0.0.1

virtual_maps = hash:/etc/postfix/virtual

---

The thing is that when am sending email using przemk0@server.com it goes
from IP 210.210.210.210 :
Received: from server.com (unverified [210.210.210.210])

and i want to send my mail's from : 210.210.210.214

I was trying maybe to change myhostname to mail.server.com and mydomain
and myorigin to server.com, it didnt work :

Received: from mail.server.com (unverified [210.210.210.210])

Help :)

See "man 5 postconf" for "inet_interfaces":

"When inet_interfaces specifies just one IPv4 and/or IPv6 address that
is not a loopback address, the Postfix SMTP client will use this
address as the IP source address for outbound mail."

---<main.cf>---
inet_interfaces: 210.210.210.214, 127.0.0.1

As you can see in my message, i have :

inet_interfaces: 210.210.210.214, 127.0.0.1

in my configuration file.. and it is not working :/

Run the command: postconf inet_interfaces

and verify that the value is: 210.210.210.214, 127.0.0.1

If it's not, then there's a duplicate entry in the main.cf file.

If it is, and a "postfix reload" doesn't fix the problem, then I
don't know what else the problem could be,

I solve this problem (someone from polish linux debian grup help me)..
there was empty "smtp_bind_address" and it should to be :

smtp_bind_address = 210.210.210.214

Thx anyway for your time :)
